Annotation Type Replace

@Retention(value=RUNTIME)
 @Target(value={METHOD,CONSTRUCTOR})
 @Documented
public @interface Replace

This annotation allows the programmer to substitute a method or constructor body implementation by a TypeScript implementation.

The annotation's value contains TypeScript which is generated as is by the JSweet transpiler. The code will be checked by the TypeScript transpiler.

The replacing code can contain variables substituted using a mustache-like convention ({{variableName}}). Here is the list of supported variables:

• {{className}}: the current class.
• {{methodName}}: the current method name.
• {{body}}: the body of the current method. A typical use of this variable is to wrap the original behavior in a lambda. For instance: [before code] let _result = () => { {{body}} }(); [after code] return result;
• {{baseIndent}}: the indentation of the replaced method. Can be used to generate well-formatted code.
• {{indent}}: substituted with an indentation. Can be used to generate well-formatted code.
